基于联系数的工期求解方法

A Method of Calculating Duration Based on Connection Number

网络计划具有不确定性,即本质上是在某个区间变化着的东西,只有在特定条件下才取某个定值。以往有关工程工期网络计划的不确定性问题的研究,主要集中在PERT的研究上。自1989年赵克勤提出用联系数来研究网络计划的不确定性以来,此方法得到广大学者的青睐。应用基于联系数的网络计划,结合MCS来求解工程工期问题,实例证明了此方法的可行性和有效性。

The network plans have uncertainty,that is essentially a change in a range of things that only under certain conditions to obtain a valuation. In the past the works of the period of uncertainty in network planning studies,mainly in the PERT research. Since 1989,Zhao Keqinmade CN in studying the uncertainty of the network,this approach has been favored by the majority of scholars. In this paper,appling the network based on CN and MCS to calculate of Duration,and the method be demonstrated to be feasibility and effective.
